Working Theory

An automotive o2 sensor – had been invented by Bosch - is a small sensor inserted into the exhaust system of a gasoline engine to measure the concentration of O2 remaining in the exhaust gas to make enable an Powertrain Control Module to control the efficacy of the combustion process in the engine. In most modern vehicles, like Dodge Rampage these sensors are attached to the engine's exhaust manifold to determine whether the mix of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to your Dodge Rampage's engine management, which adjusts the mix to give the engine the best possible fuel efficiency and lowest possible exhaust emissions.

Bosch patented ceramic technology affords best-in-class performance. The ceramic element is a critical part of the o2 sensor. Bosch's patented materials and processes ensure unparalleled quality and engine performance. Also it sounds reassuringly, major vehicle manufacturers place their trust in Bosch lambda probes. Why replace? Failure of these lambda probes, either through normal aging, the use of leaded fuels, or due to fuel contamination with eg. silicones or silicates, can lead to damage of your Dodge Rampage's catalyst and expensive repairs.

Compatibility

Our Bosch exhaust oxygen sensor is available to all vehicles fitted with 1 up to 4-wire zirconia o2 sensors, torqued in M18 x 1.5mm threaded nut. This exhaust oxygen sensor will fit your Dodge Rampage if it is fitted with 1 up to 4-wire narrowband zirconia o2 sensor, upstream or downstream.

Heavy exhaust modifications like de-cats, catless exhaust systems or headers trip MIL light. In this instance the replacement of the lambda sensor will not treat MIL issues. If so, you need to wire up oxygen sensor simulator to the post oxygen sensor(s)' harness in order to get rid of Engine computer safe mode causes the engine run inefficiently ruining both power output and fuel economy.

exhaust oxygen sensors are recommended to be replaced after each 50.000 miles - 80.000 km.

Bosch Dodge Rampage exhaust air fuel sensors far outperform any other brand in regards to reliability and durability.

lambda sensors are subject to extreme conditions. A properly functioning lambda probe significantly affects the basis for reliable engine operation and thus economy, emissions, and exhaust gas values. In common sense Bosch oxygen sensors are unbeatable thanks to their long longevity, excellent operation, and optimum engine compatibility. They make a fundamental contribution to gas saving the driver money and protecting the environment.It is not unlike on your Dodge Rampage

Good to know that Bosch invented the oxygen sensor and it is first choice for lambda probes throughout the world. An annual production of around 38 million lambda probes impressively demonstrates the high quality and skill delivered by Bosch. It therefore comes as no surprise that most Customers driving Dodge Rampage preferably choose a Bosch o2 sensor when replacement interval passed.

Oxygen sensors are used to reduce vehicle emissions, by ensuring that engines burn their fuel efficiently and cleanly. Robert Bosch GmbH introduced the first automotive lambda probe in 1976. The sensors were introduced in the US from about 1980, and were required on all models of cars in many countries in Europe in 1993. By measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can use look-up tables to determine the amount of fuel required to burn at the stoichiometric ratio (14.7:1 air:fuel by mass for gasoline) to ensure complete combustion. When an internal combustion engine is under high load (such as when using wide-open throttle) the oxygen sensor no longer operates, and the engine automatically enriches the mixture to both increase power and protect the engine.

Internal Design

The sensor element is a ceramic cylinder plated inside and out with porous platinum electrodes; the whole assembly is protected by a metal gauze. It operates by measuring the difference in oxygen between the exhaust gas and the external air, and generates a voltage or changes its resistance depending on the difference between the two. The sensors only work effectively when heated to approximately 300°C, so most lambda probes have heating elements encased in the ceramic to bring the ceramic tip up to temperature quickly when the exhaust is cold. The probe typically has four wires attached to it: two for the lambda output, and two for the heater power.

Operation of the Zirconia O2 Sensor

The zirconium dioxide, or zirconia, lambda sensor is based on a solid-state electrochemical fuel cell called the Nernst cell. Its two electrodes provide an output voltage corresponding to the quantity of oxygen in the exhaust relative to that in the atmosphere. An output voltage of 0.2 V (200 mV) DC represents a lean mixture. That is one where the amount of oxygen entering the cylinder is sufficient to fully oxidize the carbon monoxide (CO), produced in burning the air and fuel, into carbon dioxide (CO2). A reading of 0.8 V (800 mV) DC represents a rich mixture, one which is high in unburned fuel and low in remaining oxygen. The ideal point is 0.45 V (450 mV) DC; this is where the quantities of air and fuel are in the optimum ratio, called the stoichiometric point, and the exhaust output will mainly consist of fully oxidized CO2. The voltage produced by the sensor is so nonlinear with respect to oxygen concentration that it is impractical for the electronic control unit (ECU) to measure intermediate values - it merely registers "lean" or "rich", and adjusts the fuel/air mixture to keep the output of the sensor alternating equally between these two values. This type of sensor is called 'narrow band', referring to the narrow range of fuel/air ratios to which the sensor responds. The main disadvantage of narrow band sensors is their slow response: the control unit determines the exhaust gas composition by averaging the high and low swings in the sensor's output, and this process creates an inevitable delay Not quite sure this oxygen sensor fits your vehicle?

readings were as low as a brand new car

I changed all 4 of the o2 sensors on my G36 AMG. Fortunately the old ones screwed out easily. These new bosch sensors fit perfectly. I had the car smog tested a week after and the tech guy was shocked by my test results. He said my o2 sensor readings were as low as a brand new car.

difference was remarkable

I installed a fuel pac 3 months ago and purchased a set of four Bosch Sensors from Magnum last week for my GMS Savana. They shipped from stock the universal set-up o2 sensors at very affordable price. After installed the tuner I didn’t noticed marked improvement in power, I then proceeded to replace the 4 o2 sensors. I did not have any issue with the installation. Since all sensors expect for the right bank one are accessible they only needed some penetrating oil to remove. Installation is a breeze. Afterwards difference was remarkable. Truck came to life. I am very pleased.

its genuine bosch

Ordered to my car and it arrived ahead of schedule. O2 Sensor matched original signal wise and worked just right, its genuine bosch and price was fair but in return wiring sucks if you have no crimping tool. I didnt have. All in all 4-star despite their techs put every wheel into motion to guide me through the set up.

Bosch had been an OEM supplier

I bought these sensors for my 1997 Voyager at a local parts store for $95 a piece. I looked at (removed) and they less expensive so returned them and paid for negligible restocing fee. I was completely comfortable ordering them online because magnum made sure they are compatible with your car and I knew Bosch had been an OEM supplier so they would last a long time. Sensors were easy to install and plugged right into my factory harness. Whenever I have to buy oxygen sensors again, I'm definitely checking with magnum.
